I'm looking into exhibition mode for Squeeze Control and I trying to decide how much functionality I should put into that mode.

One end of the spectrum would be a simple Now Playing screen with playback and volume controls. The other end would be a mini app with three screens (Now Playing, Current Playlist, Player Manager), the ability to switch players, and repeat, shuffle, sleep controls.

I'm leaning towards the simple version, since I'm not sure if the complex version is worth the effort for a mode that's meant more for display.

I would also vote for a simple version. If you want all functionality it's not that much fuzz to swipe up and leave exhibition mode.
A little bit of some sort of additional visualisation would be cool though. A Clock for example.
